我尝试显示当前用户的帖子，帖子ID和用户ID相同，当我具体到列表视图代码时出错（

snapshot.data!.docs.map((DocumentSnapshot document))

我得到了这个错误：
没有为类型"DocumentSnapshot〈Map〈String，dynamic〉〉"定义getter "docs"。请尝试导入定义"doc"的库，将名称更正为现有getter的名称，或者定义getter或字段名称"docs"。
我该怎么办？我做错什么了？
我的代码：

class MyRidesScreen extends StatefulWidget {
  const MyRidesScreen({super.key});

  @override
  State<MyRidesScreen> createState() => _MyRidesScreenState();
}

class _MyRidesScreenState extends State<MyRidesScreen> {
  Stream<DocumentSnapshot<Map<String, dynamic>>> myPosts = FirebaseFirestore
      .instance
      .collection('ADS')
      .doc(FirebaseAuth.instance.currentUser!.uid)
      .snapshots();

  @override
  Widget build(BuildContext context) {
    return StreamBuilder(
        stream: myPosts,
        builder: (BuildContext context, snapshot) {
          if (snapshot.hasError) {
            return const Center(
                child: Text(
              'Error occured',
              style: TextStyle(fontSize: 20),
            ));
          }
          if (!snapshot.hasData) {
            return const Center(child: Text('No requests yet'));
          }
          if (snapshot.connectionState == ConnectionState.waiting) {
            return const Center(child: Text("Loading"));
          }

          return ListView(
            children: snapshot.data!.docs.map((DocumentSnapshot document) {
              Map<String, dynamic> data =
                  document.data()! as Map<String, dynamic>;
              return Card(
                child: ListTile(),
              );
            }),
          );
        });
  }
}
